319 dnl pcre, pcreposix, pcrs and gnu_regex:
321 dnl The presence of shared pcre, pcreposix or pcrs
322 dnl libraried is now autodetected. Additionally, the
323 dnl user can enforce using the built-in static variants
324 dnl by specifying --disable-dynamic-(pcre|pcrs).
325 dnl Care is taken to avoid that pcre is dyn, while pcreposix
326 dnl is static, if both are used and that pcrs is static if
329 dnl The choice between pcre, gnu or no regex for actionsfile
330 dnl URL matching is now via
331 dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the
332 dnl default being pcre.
334 dnl Revision 1.6 2001/06/29 21:56:40 oes
337 dnl Revision 1.5 2001/06/29 13:26:27 oes
338 dnl Introduced #define CODE_STATUS
340 dnl Revision 1.4 2001/05/29 09:50:24 jongfoster
341 dnl Unified blocklist/imagelist/permissionslist.
342 dnl File format is still under discussion, but the internal changes
343 dnl are (mostly) done.
345 dnl Also modified interceptor behaviour:
346 dnl - We now intercept all URLs beginning with one of the following
347 dnl prefixes (and *only* these prefixes):
349 dnl * http://ijbswa.sf.net/config/
350 dnl * http://ijbswa.sourceforge.net/config/
351 dnl - New interceptors "home page" - go to http://i.j.b/ to see it.
352 dnl - Internal changes so that intercepted and fast redirect pages
353 dnl are not replaced with an image.
354 dnl - Interceptors now have the option to send a binary page direct
355 dnl to the client. (i.e. ijb-send-banner uses this)
356 dnl - Implemented show-url-info interceptor. (Which is why I needed
357 dnl the above interceptors changes - a typical URL is
358 dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
359 dnl The previous mechanism would not have intercepted that, and
360 dnl if it had been intercepted then it then it would have replaced
361 dnl it with an image.)
363 dnl Revision 1.3 2001/05/22 18:46:04 oes
365 dnl - Enabled filtering banners by size rather than URL
366 dnl by adding patterns that replace all standard banner
367 dnl sizes with the "Junkbuster" gif to the re_filterfile
369 dnl - Enabled filtering WebBugs by providing a pattern
370 dnl which kills all 1x1 images
372 dnl - Added support for PCRE_UNGREEDY behaviour to pcrs,
373 dnl which is selected by the (nonstandard and therefore
374 dnl capital) letter 'U' in the option string.
375 dnl It causes the quantifiers to be ungreedy by default.
376 dnl Appending a ? turns back to greedy (!).
378 dnl - Added a new interceptor ijb-send-banner, which
379 dnl sends back the "Junkbuster" gif. Without imagelist or
380 dnl MSIE detection support, or if tinygif = 1, or the
381 dnl URL isn't recognized as an imageurl, a lame HTML
382 dnl explanation is sent instead.
384 dnl - Added new feature, which permits blocking remote
385 dnl script redirects and firing back a local redirect
387 dnl The feature is conditionally compiled, i.e. it
388 dnl can be disabled with --disable-fast-redirects,
389 dnl plus it must be activated by a "fast-redirects"
390 dnl line in the config file, has its own log level
391 dnl and of course wants to be displayed by show-proxy-args
392 dnl Note: Boy, all the #ifdefs in 1001 locations and
393 dnl all the fumbling with configure.in and acconfig.h
394 dnl were *way* more work than the feature itself :-(
396 dnl - Because a generic redirect template was needed for
397 dnl this, tinygif = 3 now uses the same.
399 dnl - Moved GIFs, and other static HTTP response templates
402 dnl - Some minor fixes
404 dnl - Removed some >400 CRs again (Jon, you really worked
407 dnl Revision 1.2 2001/05/20 01:21:20 jongfoster
408 dnl Version 2.9.4 checkin.
409 dnl - Merged popupfile and cookiefile, and added control over PCRS
410 dnl filtering, in new "permissionsfile".
411 dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
412 dnl file error you now get a message box (in the Win32 GUI) rather
413 dnl than the program exiting with no explanation.
414 dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header
416 dnl - Removed tabs from "config"
417 dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition.
418 dnl - Bumped up version number.
